Regular Input Port
This block represent a regular input port. It must only be used inside a Xcos Super Block and be connected to a regular input in the subsystem.
This block is a signal link from outside of a system into a sub-system. In a Super Block, the regular's input ports must be numbered from 1 to the total number of regular's input ports. You can set it with the Port number parameter.
Output : same type that the input connected to it in the sub-system.
An integer defining the port number.
Properties : Type 'vec' of size 1.
always active: no
- port 1 : size [-1,-2] / type -1
number/sizes of activation inputs: 0
number/sizes of activation outputs: 0
continuous-time state: no
discrete-time state: no
object discrete-time state: no
name of computational function: input
In the following example the Super block is an amplitude modulator. The IN_f block is used as a modulation signal input. Its data type is defined by the input type of the gain block that is a scalar double data type.
The following figure shows the output of the bloc :
